ISL78213ARZ

Voltage Regulators - DC DC Switching Regulators Overview

The ISL78213ARZ is a synchronous buck switching regulator IC manufactured by Renesas Electronics. It provides a positive adjustable output voltage starting from 0.8V with a maximum continuous current of 3A. The device operates with a fixed switching frequency of 1MHz (1200kHz max) and accepts an input voltage range up to 5.5V. It is housed in a 16-lead VQFN package with an exposed pad, designed for efficient power conversion in space-constrained applications.
